VE NEER-MACHINE Specification of Letters Patent.

T o all whom it may concern:

Be it known that I, HARRY T. VVrLLIAMs, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Veneer-Machines, and I do declare the following to be a full, clear, and exact description of the invention, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to machines for making veneering by sawing operations, and the invention has reference more particularly to veneer saws and the mountings thereof.

The objects of the invention are to provide a veneer machine that will be adapted to produce relatively broad strips of veneering by means of a circular saw having relatively small diameter; to provide a veneer machine of novel construction whereby in carrying out the above-inentioned object the saws may bequickly removed from the machine to .be resharpened while replaced by a sharpened saw so that the operations of the machine need not be delayed while re-sharpening the saws, thus avoiding lost time in the operations of the machine; a still further object being to provide useful improvements in veneer saws and their mountings.

IVith the above-mentioned and minor objects in view, the invention consists in a veneer saw flange v.mounted removably on a spindle or rotative shaft whereby to facili-l tate the changing of saws; and the invention consists further in the novel parts and the combinations and arrangements of parts as hereinafter particularly described and referred to in the following claims.

Referring to the drawings Figure l is a top plan of the improved machine partially broken away; Fig. 2; a transverse vertical sectional view approximately on the axis of the veneer saw; Fig. 3, a front elevation of the improved saw and its support in which some of the saw blades are omitted from the saw flange; Fig. 4, a fragmentary side view of the saw spindle; Fig. 5, a fragmentary central sectional view of the saw flange; Fig. 6, a front elevation of the saw spindle and its support; Fig. 7 a fragmentary front elevation of the saw flange; Fig. 8, a transmounted on its spindle; Fig. 9, an elevation of the mountings of the saw spindle; and, Fig. l0, a rear elevation of the saw flange partially broken away.

Similarv reference characters in the different figures of the drawings designate corresponding elements or features of construction.

In practically carrying out the invention a suitable frame is provided com rising supports A and A which are suitab y mounted either on a suitable foundation or on a mill floor, and they support a pair of journal bearings B and B provided respectively with bearing caps C and C. A spindle or shaft D is mounted rotatively in the bearings and caps thereof and is provided with a collar D for preventing longitudinal movement theref. A pulley E is attached to the spindle and is driven by a belt F which may conveniently run through the mill floor to any suitable driving means beneath. The front end of the shaft D that is near the bearing B has a tapering extremity D2, rearward of which a collar G encircles the shaft D with a tight fit thereon and is usually further secured by a key H to the shaft. The face of the collar is straight, the rear side thereof being beveled or somewhat like the frustum of the cone. A suitable number of threaded studs as I or I are secured to the collar and project forwardly beyond the straight face thereof so that they are arranged around the tapering portion D2 of the spindle, the studs being provided for the double purpose of securing thesaw flange to the spindle and its collar; and for driving the flange and thereby the veneer saw. The collar G is provided also with a pair of screws J and J that are mounted in the collar with their heads at the rear thereof so that the points of the screws may be projected through and beyond the straight face of the collar to force the iange from the tapering end D2 of the spindle, the screws being arranged at opposite sides of the spindle in holes K andK that are provided in the collar to receive them. The studs I or I are provided each with a nut L.

The saw flange M has a straight front face and beveled rear, being disk shaped as usual, and in the center thereof has a tapering hole M adapted to fit on the tapering portion D2 of the spindle D so that the flange may alverse sectional view of the saw flange i ways be depended upon to be tight on the spindle and run true, the back of the flange having a recess N adapted to fit against the collar G, there being bolt holes O extending through the flange to receive the studs I or I, the outer ends of the bolt holes being greater in diameter than the inner portions of the holes, so that recesses O are formed in the face of'the flange to receive the nuts L. A suitable number of saw blades I? or P are suitably secured to the peripheral portion of the sawflange and are removable so that they may be replaced by new ones when necessary. In the rear of the flange M is a threaded hole Q to receive a cap screw Il whereby to secure a hook S to the flange temporarily by means of a suitable shank S- with which the hook is provided so that a traveling hoist T may be connected with the hook for conveying the flange either way from or to the saw spindle when changes are desired.

A pair of track rails U and U are suitably supported in a plane below the plane of the spindle D and a suitable carriage Vis mounted so as to travel longitudinally on the rails at the front of the saw, the carriage having a transversely adjustable head Wv mounted thereon that is provided with dogs X and X for holding the flitch or slab Y from which to saw the veneering. The lowermost dog X is arranged in a plane but slightly above the horizontal plane of the spindle D so that the bottom of the flitch will pass above and relatively close to the axis of the spindle, thus requiring a saw of less diameter than has usually been employed when the saw spindles have been provided with bearing supports at the front of the saw, such supports usually being devoid of bearing caps in order to avoid obstructing the path of the flitch, but in any case preventing the flitch from passing near the axis of the saw, which disadvantage as will be apparent is overcome in the present invention.

In practical use the flange M is secured to the spindle I) and its collar G as hereinbefore described, and the hook S and screw bolt R are to be detached from the flange and the machine may then be operated in the usual manner, and when the saw blades or segments P or Pf become dull the machine may be stopped, the hook S applied to the flange M then the screws J and J may be turned to dislodge the flange from the spindle after which the flange may be drawn off of the studs I or I, the nuts L having been previously removed as will be understood, and by means of the traveling conveyer T the flange may be transferred -to a suitable point in the mill and deposited, and then by means of the conveyer another flange, the saws of which have been previously sharpened may be instantly conveyed and connected to the spindle and the flange G in the manner which will be understood from the foregoing description, and while using the sharpened saw the other' one may' be reshar ene'd so as to be' ready for the next change t at may be required. j
